Just getting started, what hardware?
The 2nd system would be better at rendering only using the CPU, but the 1st system would be better at rendering with CPU + GPU combined, along with running EEVEE better, since it uses a dedicated GPU. I'd suggest the 1st system, since the GPU should be able to pick up the slack of the weaker CPU, though you'll have to go into Blender's settings to enable Blender to use the GPU at all. (Also the fact that rendering with only GPU is faster than rendering with only CPU. Still turn both on though.)

Go to Preferences > System and tick off both CPU and GPU to enable this.
